A man has been arrested after a firearms incident in South Auckland this afternoon.

The man will appear in the Papakura District Court tomorrow charged with two counts of unlawful possession of a firearm.

After police arrested the man, they found a loaded firearm in his car and another in his house in the Hunua area.

A number of other firearms and ammunition were also seized.

Detective Senior Sergeant Aaron Proctor said the community should not be concerned.

"The seizure was required due to the man's actions earlier in the day. While the carriage and storage of them was in breach of the Arms Act requirements, we are confident that the community is not in danger," he said.
